any of the named files are already versioned.
258
259
In recursive mode (the default), files are treated the same way
260
but the behaviour for directories is different. Directories that
261
are already versioned do not give a warning. All directories,
262
whether already versioned or not, are searched for files or
263
subdirectories that are neither versioned or ignored, and these
264
are added. This search proceeds recursively into versioned

directories. If no names are given '.' is assumed.

Therefore simply saying 'bzr add' will version all files that

are currently unknown.

implicitly add the parent, and so on up to the root. This means

get added when you add a file in the directory.

2064
2065
The branch is the branch you will merge from. By default, it will merge
2066
the latest revision. If you specify a revision, that revision will be
2067
merged. If you specify two revisions, the first will be used as a BASE,
2068
and the second one as OTHER. Revision numbers are always relative to the
2069
specified branch.
2070
2071
By default, bzr will try to merge in all new work from the other
2072
branch, automatically determining an appropriate base. If this
2073
fails, you may need to give an explicit base.
2074
2075
Merge will do its best to combine the changes in two branches, but there
2076
are some kinds of problems only a human can fix. When it encounters those,
2077
it will mark a conflict. A conflict means that you need to fix something,
2078
before you should commit.
2079
2080
Use bzr resolve when you have fixed a problem. See also bzr conflicts.
2081
2082
If there is no default branch set, the first merge will set it. After
2083
that, you can omit the branch to use the default. To change the
2084
default, use --remember. The value will only be saved if the remote
2085
location can be accessed.
2086
2087
Examples:
2088
2089
To merge the latest revision from bzr.dev
2090
bzr merge ../bzr.dev
2091
2092
To merge changes up to and including revision 82 from bzr.dev
2093
bzr merge -r 82 ../bzr.dev
2094
2095
To merge the changes introduced by 82, without previous changes:
2096
bzr merge -r 81..82 ../bzr.dev
2097
2098
merge refuses to run if there are any uncommitted changes, unless

--force is given.
